Yet you can do so by using higher strength materials, more technically advanced reactors and power transfer systems (which are more expensive). There is no real reason why a ship as big as a Sabre wouldn't have the same endurance as one. Replacing the ships with completely new models might be done at some point, but frankly, we don't have the modellers for that kind of ship replacement project at this point - and the vanilla ships work fine.
Wide awake in a world that sleeps, enduring thoughts, enduring scenes. The knowledge of what is yet to come.
From a time when all seems lost, from a dead man to a world, without restraint, unafraid and free.
